Several Updates to MultiMarkdown CMS

There have been many changes to MMD CMS throughout the
week. I rewrote much of the code to be more uniform, fixed a fair number of
bugs, and streamlined a few things.

The biggest change is in the requirements for how it is hosted. There are now
two branches - the regular branch, and the advanced branch. The differences in
purpose and configuration are detailed on the project page, and in the README.
